[MAIPC] Corydalis incisa: be on the lookout

Thu Apr 14 05:33:40 PDT 2016

Is anyone reporting this? I only see one infestation reported to EDDMapS. Let me know if the info is going to a different database, so we can see if they will share the data. I am hearing about this species more and more.
Thank you!Karankrawlins at uag.edu

 Re: [MAIPC] Corydalis incisa: be on the lookoutUnfortunately, 4 of us went out to Confederate Fortifications on Sunday, & found lots. We pulled & dug plants for nearly 4 hours, & didn’t come anywhere near the end of them: they appear to be coming down the waterway (Little Rocky Run) from somewhere unknown upstream. My personal opinion: this one is out of the bag & won’t be going back in. (Have also found 3 plants in my own yard, on the banks of a completely different waterway, that eventually feeds into Holmes Run.)

Erin, that’s great. I will say that I thought I pulled all of it in the area  last year, but went back the other day and found some adjacent to the area where I pulled it up last year. Did I just miss that spot last year? Who knows? But I also wonder about a seed bank and I wonder if anyone knows about that.

The Corydalis incisa found in Confederate Fortifications in Fairfax County last year was removed before it went to seed. There was only a handful of mature plants.  It was found in pretty much the same habitat I would expect to find lesser celandine.

Ruth,

Perhaps Susan told you this already, but perhaps that near-Wolf Trap sighting was what we found last year or two years ago at Confederate Fortifications, along Bull Run I believe in Fx. County.  The plant was up close to the road along the trail used by the Grass Group to enter the park.  Margaret might be able to patrol in the area again and see if it is spreading.

Thanks, Milo. One point for us all is that the Plants fact sheet does not have any locations for this plant outside of NY State, and we should all look into that. Does anyone know how one goes about “registering” a plant location with them?  And I suppose that there is some sort of review process that goes on before any data point is noted. I think I recall that last spring someone reported this plant near Wolf Trap in Nrn. Va. Here is a link to the Digital Atlas of Virginia Flora with a brief note about the plant http://www.vaplantatlas.org/index.php?do=plant&plant=4568&search=Search <http://www.vaplantatlas.org/index.php?do=plant&plant=4568&search=Search>  

Best,

Purple or white flower color looks like a pretty clear identifier — according to Flora of Virginia, we only have one native Corydalis: the much smaller yellow-flowered C. flavula. C. sempervirens has pink flowers ( & has been renamed Capnoides sempervirens). Then there is Fumaria officinalis with round seedpods — and it isn’t native.

Ruth,

Just to be sure.. How do you know that this is incisa? There are a lot of native Corydalis as I'm sure you know... Some look like this. I just want to be sure the identification is correct.

Thank you!

Last year around the end of April I went looking for possible Corydalis incisa along Red Bud Creek, near my home in Albemarle Co. VA. I found probably 40 plants in bloom and starting to go to seed. I pulled up all those I saw and flagged the area. This year I went back on April 3 and found about 15 plants in bloom nearby, but not yet going to seed, and pulled them all and again flagged the area.

In the last several days I have heard of two more infestations in Virginia, one more in Albemarle Co. and one in Madison Co., both in extensive private native plant gardens. I don’t know if the plant hitchhiked in with another plant purchased from a supplier or whether the owner planted them without realizing that they could be very invasive; I will investigate that.

I don’t think I can attach a picture, but here is a link to a photo  http://www.henriettes-herb.com/galleries/photos/c/co/corydalis-incisa-1.html 

And here is a link to a plants profile http://plants.usda.gov/core/profile?symbol=COIN21
